Around my neck of the woods, hedge post are sold by word of mouth OR advertised on C.List or F.Book. Usually 10 to 20$ piece and worth every penny. The person having cut them out will have a 100 dollars worth of blood, sweat, and cuss words in every post...thorny tough ole trees! They won't be squared off. They will be "bark-on" and getting real straight ones, well that rarely happens.
I can't help with western or eastern qualities.
